Well, as you can probably guess, there is no easy answer here. We all have varying needs, some only want to block ads, others try to keep their kids safe and this is one tool in the toolshed. Others are looking to GEOBLOCK... Me, not so much geoblock, as ad blocking and 'not-nice' sites, along with blocking public DNS, together with nat rules to redirect IOT back to PFSense for DNS. It took months of trial and error to come up with a workable mix, the lists are not maintained by BBcan (with the exception of his) but by 3rd parties. List owners can change as the lists are bought by new owners sometimes. Sometimes a list works well, then not so. Sometimes they are abandoned and don't get updated or disappear. So this is not a 'set and forget'. I pop into PFSense about once a month just to check that the lists are updating, or if there are newer lists that may do better that I could test out. It's the nature of internet security; it really IS shooting ducks in a barrel...
If you've had issues in the past with it, perhaps the way to go is to wade in a little at a time. Start with IP blocking only. Select the lists that appear to do what you are looking for, example, Emerging Threats, Talos, and I use cins army. You can round it out with a coinblocker and maybe a few others in other categories. Work with those for long enough to confirm they aren't blocking things that are causing issues. You could also go to their websites and read about their lists to determine what you think is important.
Once that is stable, you can do something similar with the DNSBL lists. Nothing is turnkey here. Things take time.
